Best good grade water tank coating

[Nixx]

Thanks for all your reply’s !! Will do further digging on all epoxies reccomended

Regarding plastic tanks If you see the pics. Tanks are a structural part of the hull. Due to frames and stingers I can’t fit a plastic tank.i have 1000l of water and don’t want to change the weight distribution . Additionally a large area of my below waterline is in built tanks, I kinda like the additional safety of any penetrations being in the tanks rather than in the hull.

Man I’ve spent some time on a grinder though

In my opinion, the way to get the best water on a boat is to pick your poison with tanks, and then do just what you did. Filter it through carbon filters and you can’t taste a thing.

What I typically do is a polyethylene tank followed with some bleach treatment, just a light bit, to make sure nothing can grow in there, then it goes through carbon filtration. Just like your wife says. Better than the water you can get anywhere else. Including bottled water and tapwater.

The metallic taste is from aluminum tanks. Stainless steel is tasteless, all the good water bottles are stainless

You say that because you are used to it.

I would say the same thing about plastic tanks because I am used to them.

However, all tanks leave a taste in the water. All of them. I can taste stainless a mile away. It’s gross. So is plastic. I’ve never had the misfortune of aluminum.

In theory a perfectly built stainless tank shouldn't leave any taste in the water. But if there's anything less than perfect about the tank (either poor choice of stainless grade, welds not perfectly smooth and can trap stuff, etc.) it could. And the rest of the system plumbing, pumps, etc. all have a chance to leave a taste in the system as well. And it'll depend some on the water going in as well. Water that's a bit off in pH or other factors could cause more interaction with materials in the water system.

The stainless steel water bottles have the best water I ever tasted, just as good as from glass.

You can taste the difference from the same water, between chilled in a glass bottle or a stainless bottle?

I remember those anodized aluminum glasses… horrible
